Fix logging at -v 2

[mdbooth]

We currently output NO LOGS at our default log level of -v 2. We should output at least resource creation and deletion events at -v 2.

Lets follow the conventions at https://github.com/kubernetes/community/blob/master/contributors/devel/sig-instrumentation/logging.md

Additionally, lets define some constants with easily-understandable names for each of the log levels, and use these constants consistently throughout the codebase.
